Okay, you pop music fans — here’s another upcoming album to get excited about! Katy Perry revealed that her fourth studio album Prism will be available on Oct. 22, and she made the announcement via a gold semi-truck traveling around Los Angeles.

After a fan initially spotted the truck, Katy tweeted, “Find the #PRISM semi, take a picture and I’ll RT you.” And don’t worry non-LA folks…the singer added that the truck will also make rounds outside the City of Angels.

Later, Katy’s pal Johnny Wujek spotted the semi truck himself and uploaded a photo to Instagram. In the caption he added, “Get ready to be enLIGHTened#you’reGonnaflip #everysongisaHit.” Well, come on — didn’t we already know that every Katy Perry song is a hit?!

Besides Katy, Lady Gaga recently announced that her album will be coming this fall, as well. Lots to look forward to!
